Abstract
In real-time three-dimensional imaging the choice of the visualization method and orientation is crucial for intervention success. The key question is what to ignore and what to show in real-time applications, where user control is not appropriate. An intervention (caused by a user) to an object of interest is visualized without the requirement of an interactive input by the user. Parameters for a visualization procedure are automatically chosen during data acquisition which may allow for an efficient tracking of the actual orientation and relative position of the structure with respect to the object of interest.
Claims17
A method of visualizing a multi-dimensional data set, the method comprising:
- with one or more processors, performing a segmentation of a structure in the data set;
- and
- with one or more processors, performing a visualization of the data set, the visualization being performed on the basis of visualization parameters comprising a projection direction, the visualization parameters being determined on the basis of at least one of the segmentation and a low-level analysis of the data set and the visualization parameters being selected from a relative position of the structure, a direction relative to the structure, a distance between the structure and an object of interest, a motion estimation, and a motion compensation;
- wherein a projection direction of the visualization is determined on the basis of the structure.
An image processing device for visualizing a multi-dimensional data set, the image processing device comprising:
- a memory for storing the data set;
- an image processor adapted for performing the following operations:
- loading the data set,
- performing a segmentation of a biopsy needle in the data set, and
- performing a visualization of the data set on the basis of visualization parameters, the visualization parameters being determined on the basis of at least one of the segmentation and a low-level analysis of the data set and the visualization parameters being selected from the group including a relative position of the structure, a direction relative to the structure, a distance between the structure and an object of interest, and a motion estimation;
- wherein a first projection of the data set is performed in a direction of a longitudinal axis of the biopsy needle, resulting in a first image with an image surface area perpendicular to the direction of the longitudinal axis;
- and
- wherein a second projection of the data set is performed in a direction perpendicular to the longitudinal axis of the biopsy needle, resulting in a second image comprising the biopsy needle.
An imaging system comprising:
- a memory which stores a multi-dimensional data set;
- an image processor which performs a visualization of the data set, the image processor being programmed to:
- load the data set,
- segment an inserted end of a surgical instrument in the data set, and
- perform a visualization of the data set including performing a first projection of the data set in a direction of a longitudinal axis of the inserted end of the surgical instrument, resulting in a first image with an image surface area perpendicular to the direction of the longitudinal axis and performing a second projection of the data set in a direction perpendicular to the longitudinal axis of the inserted end of the surgical instrument, resulting in a second image including the inserted end of the surgical instrument.
A tangible computer readable medium carrying a computer program for controlling one or more processors to perform a visualization of a multi-dimensional data set including:
- loading the data set;
- performing a segmentation of a structure in the data set;
- determining visualization parameters on the basis of at least one of the segmentation and low-level analysis of the data set, the visualization parameters including one or more of a relative position of the structure, a direction relative to the structure, a distance between the structure and an object of interest, a motion estimation, and a motion compensation;
- and
- performing a visualization of the data set including projecting the data set in a projection direction based on the visualization parameters.
An imaging system comprising:
- an imaging device that generates image data during an interventional procedure in which an interventional structure is inserted in an imaged object;
- an image processor programmed to:
- segment the image data,
- analyze the segmented image data to determine one or more viewing directions based on the interventional structure in the segmented image data without operator input,
- project the segmented data set along the one or more viewing directions;
- and
- a display device on which images of the one or more projected segmented data sets are displayed.
